PETROGALE LATERALIS, Govld, 
Stripe-sided Rock- Wallaby. 
Upper Half of the Animal, of the size of life, and a reduced figure 
IN THE DISTANCE. 
This is the West Australian representative of the P. penicillata of New South Wales; in 
size it is somewhat smaller than that animal, hut its markings are more strongly defined. 
In the eolony of Swan River, roeky distriets alone are the plaees of its resort. In their 
dispositions and general eeonomy the P. lateralis and P. penicillata are very similar. I 
always observed that the furry eoat of the former is thieker or more dense than that of 
the latter ; this differenee, however, eannot he depieted, hut is readily seen when skins 
of the two animals are seen side hy side. 
The reader is referred to the page aeeompanying the sueeeeding Plate for a more de- 
tailed Recount of this species.
